Internal tools and dashboards for agencies

Internal tools development means building the small private application a client’s team uses every day, such as a quote builder or a job tracker. We build it under your agency’s brand, and the client owns the code, the data and the hosting account at handover.

When internal tools development beats the spreadsheet

A custom tool pays off when the spreadsheet starts causing mistakes the business can count. Common signs are wrong prices on quotes, jobs lost between tabs and a sheet only one person understands.

It also pays off when different people need different views. A spreadsheet struggles to hide margins from a sales rep or show who changed a price last Tuesday.

Dashboards come in here too. When the tool holds the data, the numbers the team checks each morning sit on the same database, so nobody reconciles two versions.

Build, buy or keep the spreadsheet

We will tell you when a build is the wrong answer. Our advice depends on the situation:

Situation	Our advice
Off-the-shelf software fits the process with small compromises	Buy it, and connect it to the client’s other tools with workflow automation
One or two people use the sheet and the data is not sensitive	Keep the spreadsheet, and add validation and protected ranges
Several people edit it, roles matter, or it holds customer data	Build an internal tool with roles and an audit trail
Customers or suppliers need to log in too	Build a portal, covered by our Next.js apps on PostgreSQL service

What we build into every tool

Every tool gets roles, an audit trail, careful imports, exports and tested backups. These details decide whether the team still trusts it a year later:

• Roles designed with the client: who can see costs, who can approve and who can only add records
• An audit trail: every change recorded with the person and the time, so a disputed edit can be traced
• Imports that expect real spreadsheets: merged cells, duplicate rows and dates typed as text are caught in a validation report before anything is written
• Exports to CSV: the client’s data is never trapped in the tool
• Backups with a tested restore: we prove the backup works before the team relies on it

By default, tools run on Vercel with a managed PostgreSQL database, in an account the client owns. Email notifications go out through Resend from the client’s own domain.

Pricing, ownership and support

Each tool starts with a half-day scoping workshop and a written spec with screens. You then get a fixed price, and nothing starts until you approve it. If you run several builds at once, compare the monthly plans on our rates page.

At handover the repository transfers to you or your client, with training notes and a maintenance plan. We revoke our access and confirm it in writing, as our security page describes.

Some tools need a step that reads free text, such as supplier emails. That part is scoped under our white-label AI automation service.
